Search for it with HAILERS name he has posted it before. I would not use the TII harness to much headaches involved.

Pin 2K is the output for the Twin Scroll solenoid on a TURBOII ECU.

Pin 2K is the output for the Split Air Solenoid on a NON TURBO ECU.

So all you have to do is find the Split Air Solenods wire in the engine bay, first. The Split Air Solenoid itself was on the ACV. The aft solenoid on the ACV. It had a pigtail harness on that solenoid that connected to a connector NEAR the water thermostat housing or near the water pump housing, your pick.

THat connector has a black/white wire and a blue/black wire on the harness side of the plug. The black/white wire is the power wire and is common to the black/white wire at all the solenoids.

Twin scroll solenoid should have a green plug on it and is located on the front of the vacuum rack. You should be able to see a small white/geen check valve just fwd and inboard of the solenoid.

So what you can do is simple. Buy some 18-22 gauge wire at the auto store. Put a spade connector on one end of the two new wires you making, and put those spades in the plug you just found with the black/white and blue/black wires in it.

Run the two wires anyway you desire, over to the Twin Scroll Solenoid that came with your turbo engine, and put a couple of female spade conenctors on that end of the two wires. Install the females on the Twin Scroll Solenoid. It matters not which pin they go on, on the solenoid.

Nobody with a lick of sense would install a turbo EM harness on a non turbo car if they have a reasonably good n/a EM harness. If you look at the wiring diagrams in the FSM and the plugs called X-16, X-16, sometimes called FEM-01 or FEM-02, then anybody would realize a turbo em harness in a na is not desireable.

Where did you get your swap? I am looking for a place to order a JDM TII setup, and I would rather get one from someplace that sends reliable (able to run without a rebuild) motors.
